Formed elements of blood – erythrocytes
-
Adult human RBCs are enucleate. Which of the following statement(s) is/are most appropriate explanation for this feature? (a) They do not need to reproduce (b) They are somatic cells (c) They do not metabolize (d) All their internal space is available for oxygen transport
Loss of nucleus maximises space for haemoglobin.
In human RBCs, the nucleus degenerates during maturation, which provides more space for the oxygen-carrying pigment (haemoglobin). RBCs lack most cell organelles, including mitochondria, so they respire anaerobically (they do metabolise).
